Follow-up: your dentist or an oral and maxillofacial specialist explains the findings and plans any extraction, root treatment or further imaging.
The full picture
What this test involves, and how to get it
An OPG (orthopantomogram) is a panoramic X-ray that captures the full upper and lower jaws, all the teeth and the temporomandibular joints in one image. Dentists and oral surgeons use it to plan wisdom tooth removal, assess infections and cysts, check bone levels in gum disease and evaluate the jaws before implants or orthodontics. You stand with your chin on a rest while the arm of the machine sweeps around your head; the scan is quick, painless and delivers a small radiation dose.
OPGs are available through NHS dental services when clinically justified, though access depends on your practice and local referral pathways. Privately, most dental hospitals, imaging centres and larger practices offer OPGs within days, usually with a referral from your dentist; implant and orthodontic assessments may add a cone beam CT for three-dimensional detail. Images can be shared with your ongoing dentist so treatment planning continues seamlessly, and prices are confirmed when you book.

Frequently asked
Common questions about Dental X-rays (OPG).
Quick, plain-English answers to what people ask us most.
-
What is Dental X-rays (OPG) and what does it show?
Dental X-rays (OPG) is an imaging or diagnostic procedure that allows doctors to look at the relevant part of the body in detail, helping to identify or rule out specific problems. It gives information that usually can't be obtained from a physical examination or blood test alone. The findings are interpreted alongside your symptoms and medical history.
-
Why might a doctor request it?
It's usually requested to investigate specific symptoms, follow up on a previous finding, or check on a known condition. It may also form part of a wider screening or health assessment package. Your doctor will explain what they're hoping to see or rule out before referring you.
-
Do I need to prepare beforehand?
Preparation varies — some procedures require fasting, a full or empty bladder, stopping certain medications, or avoiding specific products beforehand, while others need no preparation at all. Because requirements are specific to this exact procedure, always follow the instructions given by the clinic at booking rather than assuming. Arriving properly prepared reduces the chance of the appointment needing to be rescheduled.
-
What happens during the procedure?
You'll usually be guided through each step by trained staff, and most of these procedures are performed with you either lying still, seated, or in a specific position for a short period. Depending on the exact test, it may take anywhere from a few minutes to around an hour. Staff will explain what to expect and answer any questions before you begin.
-
Is it painful, and are there any risks?
Many imaging procedures are painless or involve only mild, brief discomfort, though some more invasive tests may involve sedation or a small associated risk that will be explained beforehand. Serious complications are uncommon with modern techniques and experienced practitioners. You'll be given specific information about risks relevant to your particular procedure and health background before you consent.
-
How long does it take to get results?
Results are typically reviewed by a specialist and reported within a few working days, though timeframes can vary depending on complexity. Some findings may be discussed with you immediately after the procedure, with a full written report to follow. The clinic will confirm the expected timeframe when you book.
-
What happens if something abnormal is found?
If the results show something unexpected, a specialist will explain what it means and recommend appropriate next steps, which might include further imaging, a biopsy, or referral to a relevant specialist. Many abnormal findings turn out to be minor or unrelated to any symptoms once fully assessed. You'll be talked through the findings rather than left to interpret a report alone.
-
Is this available on the NHS, or is private quicker?
This type of procedure is generally available on the NHS, but routine referrals can involve a wait for both the appointment and the results. Private providers typically offer appointments within days and results reviewed by a specialist soon after, which can be helpful if you want quicker reassurance or a second opinion. Cost for private testing varies by provider.
-
How accurate is this type of test?
When performed by trained specialists on appropriate equipment, this is generally considered a reliable and clinically well-established investigation. As with any single test, results are best interpreted alongside your symptoms and other findings rather than in isolation. If a result is unclear or unexpected, further imaging or a repeat test may be recommended.
-
How do I book Dental X-rays (OPG) privately?
You can usually book directly with a private clinic, often without needing a GP referral, with appointments typically available within a matter of days. It's worth asking about preparation requirements and what the appointment will involve when you book. Contact the clinic for current availability and to discuss any specific concerns.
